My present invention per il ifi 1 I proved trenching tool, and has}for.i ts ob.

ject to provide a 'simple,-stron-g and readily convertible tool, one in-which the relation of the handle to the tool elements or members maybequic'kly changed and the parts.

firmly secured in their adjusted positions.

The invention isiillustrated in the annexed drawings, wherein: Figure lis a side elevation of the tool,

the handle standing at right angles to the tool body;

Fig. 2 a similar view showing the handle in another position;

Fig. 3 a sectional elevation, the section being taken through the handleon the line 33 of Fig. 1;

Fig. 4 a sectional view of the shank or body portion of the tool, thehandle being shown in side elevation;

Fig. 5 a sectional view on the line 5-5 of Fig. 4; and

Fig. 6 a similar view on the line 66.

The tool proper may be said to comprise a pick 1 and a shovel or spade2, connected to each other by an intermediate body or hub 3. Said bodyis provided or formed with two intersecting sockets l and 5, saidsockets standing at right angles to each other, the former lying atright angles to the major axis of the tool, while the latter issubstantially parallel therewith. Said sockets or recesses arepreferably made with a slight taper toward their inner ends, and mergeinto each other at their outer portions. The body 3 will preferably berounded or cut away, as at 6, where the walls of the two socketsconjoin, to facilitate the swinging of the handle 7 from one position ofadjustment to another.

The inner end or shank of the handle is so formed as to closely fit thesockets, 4 or 5 as the case may be, and is provided with an elongatedslot or opening 8 through which Extend a cross pin 9, the pin beingdriven or otherwise secured in openings pecificatibn o f'Letters PatentPatented N f 'fi .1917 nimati n team .49 6 s sa a sa4r1.

To facilitate the actuation of the bolts and to render their lockingengagement automatic, I preferably round or curvethat end of the handlewhich normally contacts with the bolt as the handle is pushed home, suchrounded portion being designated by 12. As will be readily appreciated,the bolt will be moved outwardly as it rides over such curved face,placing the spring under compression, the bolt being finally protrudedinto the slot when the handle is fully pushed home. I

Preferably the pick-point will be flattened, as at 13, Figs. 2 and 3, sothat it may have a fair bearing on the adjacent face of the handle whenthe parts are brought to what may be termed shovel position, thusrelieving pin 9 and the outer wall of socket 5 from undue strain.

It is evident that by making the member,

I claim is z 1. In a combined tool, the combination of a hub or bodyportion, having two sockets formed therein at substantially right anglesto each other; a tool element extending out-- Wardly therefrom; ahandle, the shank whereof is adapted'to fit in one or the other of saidsockets, said handle having an elongated opening extending therethrough;and a pin secured in the hub aforesaid and extending through theopening.

2. In a combined tool, the combination of a hub or body portion havingtwo sockets formed therein at subsiaetieili Fi g s lhatfby seesawto eachother; a tool element extending out wardly from opposite sides of saidhub; a handle, the shank whereof is adapted to fit in one or the otherof said sockets, said shank having an elongated opening extending'therethrough; a pin secured in the hub and passing through the opening;and latches mounted in the hub and associated respectively with eachsocket, said latches being wardly from the opposite side of the hub; ahandle, the shank whereof has a sliding and pivotal connection with saidhub; and means for securing the handle in one or another of itspositions with reference to the hub, the handle, when brought intosubstantial parallelism with the tool elements, bearing on the flattenedface of the first-named tool element, whereby the handle when in suchposition will be braced by the tool element against which it bears.

l. In a combined tool, the combination of a hub or body portion providedwith sockets formed therein at substantially right angles to each other;a handle, the shank whereof has a sliding and pivotal connectiontherewith, one side face' of the shank at its outer end being slightlyrounded; and a spring latch mounted in the side wall of the hub in linewith each socket, and adapted to cooperate with the shank to hold thesame in its adjusted position, said latches, respectively, riding overand being pressed outwardly by the rounded face aforesaid as the shankis moved inwardly into one or the other socket. 1

In testimony whereof I have signed my name to this specification.
